Re-piping a house is a major project, but for many homeowners, it’s a necessary one. Old, corroded, or leaking pipes can lead to water damage, poor water pressure, discolored water, and even health concerns. If your home is over 30 years old and still has galvanized steel or outdated plumbing, re-piping may not be a luxury—it’s a smart investment.
So, how much does it cost? On average, full-house re-piping in the U.S. ranges from 4,000 to15,000, depending on the size of your home, the number of bathrooms, and the type of piping material used. PEX piping, for example, is more affordable and flexible to install, while copper is more durable but costs significantly more. Labor, local code requirements, and whether walls or flooring need to be opened up also affect the final price.
Is it worth it? In most cases, yes. Re-piping improves water pressure, increases home value, and eliminates the risks that come with aging plumbing. It also means fewer leaks, fewer repair calls, and peace of mind—especially if you’re planning to stay in the home long-term or put it on the market.
Can you reduce the cost? A few strategies help:
- Choose PEX over copper for a more budget-friendly option - Re-pipe in sections if a full replacement isn’t urgent
- Time the work with other renovations to avoid paying twice for drywall or flooring repairs
- Get multiple quotes to compare pricing and scope
- Use a licensed plumber—it may cost more upfront but avoids costly mistakes
In the end, re-piping is a big decision, but if your current system is failing, it’s one that can save you money, damage, and stress in the long run.
